At Ranfac, our Integrated Product Development services ensure that your medical devices are designed with both innovation, quality and manufacturability in mind. From the initial concept and early prototyping stages through to full-scale production, our team provides comprehensive support, including Design for Manufacturing (DFM) and complete Design History File (DHF) management. Our collaborative approach streamlines the development process, reduces time to market, and ensures that your product is optimized for both performance and compliance with regulatory standards.

Machining

Consistently growing and improving to provide for our customers’ needs, our Machine Shop’s core capabilities include cutting, grinding points, laser welding, and preparing steel for over-molding. We are constantly on the forefront of technological innovation, evidenced by our array of automated equipment and creative integration of robotics to increase scale and efficiency,

Molding

Operating out of a Class 8 clean room environment, we offer both over-molding (also known as insert molding) and injection molding. Customers can take advantage of many standard mold tools, including luer lock, stylet, and cannula handles or work with Ranfac on a custom tooling project. We leverage Battenfelds and Arburgs alongside automation to maximize capacity and accuracy while reducing the cost and time to develop a new product.

Finishing

Ranfac employs ultrasonic cleaning methods using common types of acidic, neutral, and alkaline cleaners along with neutralizers and triple cascading deionized water rinsing and heated HEPA filtered dryers. We offer descaling and passivation to bolster Chromium Oxide formation on stainless steel and to remove manufacturing process oxides. We clean assemblies and mitigate risks of entrapped spaces that lead to unwanted residues.

Assembly

Ranfac’s Class 7 cleanroom for assembly offers a controlled environment for preparing products for sterilization. Built for high-mix production, our assembly room can quickly switch between diverse types of jobs. We use a mobile barcode scanning system that links directly to our ERP system and allows for real-time insights into the workflow of the manufacturing process.

Sterilization & Packaging

Ranfac guarantees finalized sterile product by managing the entire ethylene oxide (EO) sterilization process, including all requisite testing and validations. We oversee all elements from assembly to final packaging with thorough inspection and documentation. Once sterile, Ranfac transports products back to our facility for validation and packaging according to customer specifications, utilizing a wide range of packing methods to ensure product integrity.

What People Say

“Without Ranfac, I would have failed. Failed to change a process that was affecting women negatively all around the world. Ranfacʼs COO, Barry Zimble, knew the importance of this. He knew the initial process as they were already working in this space, he could use the names of the original inventors but he understood the importance of changing the manufacturing. It was their deep experience in this field that was a really important reason to go for Ranfac. Bringing a new device is a journey and it is not a straight line, you canʼt plan everything and have it all to fall in line. It is a very bumpy process, and Ranfac really was there for us with every one of these bumps. They really stuck with us and were very creative with the solution to get us back on track. We kept throwing curveballs at them and they were incredibly resilient.”

“Ranfac has supplied my company for over twenty years. We have developed a number of new products together and overcame many manufacturing and supplier issues over the years. It was always teamwork to resolve whatever challenge we incurred - no finger pointing or negotiation. It is so refreshing to share open discussions with the Ranfac team to provide quality solutions to our customers. Of course, Ranfac COO, Barry Zimble, was always actively involved as the quarterback for the Ranfac team. He's always been realistic, pragmatic and candid as we worked through our challenges. His integrity is beyond reproach. If he commits his team to a goal, you can count on them.Over the years, Ranfac has continually re-invested in their equipment, facilities and their people. When I chose Ranfac as our primary supplier, it was one of the best business decisions that I ever made.”

Ranfac was the first group—and really only group—that we approached, because I knew that they had an unparalleled reputation for putting out a very high-quality product and also they have a completely integrated facility there. They are recognized as being the best at their particular specialty and they were the sole source. What makes their products unique is quality, innovation, and response time.

“When BONESUPPORT was looking for a precise, cost-effective solution to deliver Cerament in multiple applications, Ranfac made it simple. We now have a proven technology that works easily and efficiently with our product portfolio. Thanks to Ranfac’s attention to detail and creative approach, they’ve helped us to meet the needs of our customers. Looking forward to our next project.”
